bar, e.g. for use in tabbed
dialogs.</p>
<p>QTabBar is straightforward to use; it draws the tabs using one
of the predefined <a href="qtabbar.html#Shape-enum">shapes</a>, and
emits a signal when a tab is selected. It can be subclassed to
tailor the look and feel. Qt also provides a ready-made <a href="qtabwidget.html">QTabWidget</a>.</p>
<p>Each tab has a <a href="qtabbar.html#tabText">tabText</a>(), an
optional <a href="qtabbar.html#tabIcon">tabIcon</a>(), an optional
<a href="qtabbar.html#tabToolTip">tabToolTip</a>(), optional
<a href="qtabbar.html#tabWhatsThis">tabWhatsThis</a>() and optional
<a href="qtabbar.html#tabData">tabData</a>(). The tabs's attributes
can be changed with <a href="qtabbar.html#setTabText">setTabText</a>(), <a href="qtabbar.html#setTabIcon">setTabIcon</a>(), <a href="qtabbar.html#setTabToolTip">setTabToolTip</a>(), setTabWhatsThis
and <a href="qtabbar.html#setTabData">setTabData</a>(). Each tabs
can be enabled or disabled individually with <a href="qtabbar.html#setTabEnabled">setTabEnabled</a>().</p>
<p>Each tab can display text in a distinct color. The current text
color for a tab can be found with the <a href="qtabbar.html#tabTextColor">tabTextColor</a>() function. Set the
text color for a particular tab with <a href="qtabbar.html#setTabTextColor">setTabTextColor</a>().</p>
<p>Tabs are added using <a href="qtabbar.html#addTab">addTab</a>(),
or inserted at particular positions using <a href="qtabbar.html#insertTab">insertTab</a>(). The total number of tabs
is given by <a href="qtabbar.html#count-prop">count</a>(). Tabs can
be removed from the tab bar with <a href="qtabbar.html#removeTab">removeTab</a>(). Combining <a href="qtabbar.html#removeTab">removeTab</a>() and <a href="qtabbar.html#insertTab">insertTab</a>() allows you to move tabs to
different positions.</p>
<p>The <a href="qtabbar.html#shape-prop">shape</a> property defines
the tabs' appearance. The choice of shape is a matter of taste,
although tab dialogs (for preferences and similar) invariably use
<a href="qtabbar.html#Shape-enum">RoundedNorth</a>. Tab controls in
windows other than dialogs almost always use either <a href="qtabbar.html#Shape-enum">RoundedSouth</a> or <a href="qtabbar.html#Shape-enum">TriangularSouth</a>. Many spreadsheets
and other tab controls in which all the pages are essentially
similar use <a href="qtabbar.html#Shape-enum">TriangularSouth</a>,
whereas <a href="qtabbar.html#Shape-enum">RoundedSouth</a> is used
mostly when the pages are different (e.g. a multi-page tool
palette). The default in QTabBar is <a href="qtabbar.html#Shape-enum">RoundedNorth</a>.</p>
<p>The most important part of QTabBar's API is the <a href="qtabbar.html#currentChanged">currentChanged</a>() signal. This is
emitted whenever the current tab changes (even at startup, when the
current tab changes from 'none'). There is also a slot, <a href="qtabbar.html#currentIndex-prop">setCurrentIndex</a>(), which can
be used to select a tab programmatically. The function <a href="qtabbar.html#currentIndex-prop">currentIndex</a>() returns the
index of the current tab, <a href="qtabbar.html#count-prop">count</a> holds the number of tabs.</p>
<p>QTabBar creates automatic mnemonic keys in the manner of
<a href="qabstractbutton.html">QAbstractButton</a>; e.g. if a tab's
label is "&amp;Graphics", Alt+G becomes a shortcut key for
switching to that tab.</p>
<p>The following virtual functions may need to be reimplemented in
order to tailor the look and feel or store extra data with each
tab:</p>
<ul>
<li><a href="qtabbar.html#tabSizeHint">tabSizeHint</a>() calcuates
the size of a tab.</li>
<li><a href="qtabbar.html#tabInserted">tabInserted</a>() notifies
that a new tab was added.</li>
<li><a href="qtabbar.html#tabRemoved">tabRemoved</a>() notifies
that a tab was removed.</li>
<li><a href="qtabbar.html#tabLayoutChange">tabLayoutChange</a>()
notifies that the tabs have been re-laid out.</li>
<li><a href="qtabbar.html#paintEvent">paintEvent</a>() paints all
tabs.</li>
</ul>
<p>For subclasses, you might also need the <a href="qtabbar.html#tabRect">tabRect</a>() functions which returns the
visual geometry of a single tab.</p>
